ייִדישער מחשבֿה אויף שיר השירים 4:16

(Song 4:16) “North, wake up; South, come” -- In gematria, the initial letters of the words: equal [566] Mashiach ben Yosef who first awakens in the North. As it states in the Midrash: The mashiach is in the North. Therefore the beginning of the ingathering of the exiles is from the land of the north, as is written: “behold, I will bring them from the land of the North” (Jer. 31:7). In the same chapter we find: “Efraim is My firstborn, ” and “call out on Mount Efraim, ’Rise and let us go up to Zion’” (Jer. 31: 5) etc., as explained above (#1), in the discussion of the aspect “Efraim is My firstborn.”
